Reactive and non-reactive vibrational quenching in O + OH collisions

We report a dynamics study of both reactive and non-reactive O + OH(v′,j′) collisions under local thermodynamic disequilibrium. Besides the total rate constant for temperatures over the range 110 ⩽ T/K ⩽ 450, vibrationally specific ones are reported for quantum numbers v′ ⩽ 9. Unknown thus far, such kinetic parameters may be of relevance in modelling the OH nightglow in the middle atmosphere.
